LEO FISH, OFVIBLOOMFIELD, NEBRASKA.

FEEDER FOR COBN-SHELLEBS.

Application filed February 9, 1916.

To (ZZZ whom it may concern:

Be it known that I, LEO Frsn, a citizen of the United States, residing atlBloomfield, in the county of Knox and State of Nebraska, have invented certain new and useful Improvements in Feeders for Corn-Sl1ellers,'of which the following is a specification.

My invention relates to corn shellers and appertains more particularly to an improvement in the beater arrangement of a Joliet Eureka power cornsheller.

An object of the invention is to provide and operate a secondary or auxiliary beater in advance of the common or primary beater now in use.

A further object of the invention is to so position said secondary beaterthat the corn acted on may be fed to the shelling mechanism in a most eflicacious manner and at a relatively greater speed.

I further contemplate a driving mechanism whereby said secondary beater may be rotated independently of the primary heater and through such rotation impart movement to the feed conveyer of the. machine.

As a still further object of the invention I contemplate the utilization of a belt for driving the secondary beater and the feed conveyor rather than the gearing as heretofore, for the reason that a belt will leave its associate pulley without injuring or in any way impairing the operating mechanism involved should the throat or mouth of the machine become clogged or choked for any reason whatsoever.

The above and additional objects are accomplished by such means as are illustrated in their preferred embodiment in the accompanying drawings, described in the following specification and then more particularly pointed out in the claim which is appended hereto and forms a part of this application.

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a side elevation of a Joliet Eureka corn shelling machine with my improved mechanism mounted thereon;

Fig. 2 is a similar view, the opposite side of the machine being shown;

Fig. 3 is a longitudinal sectional view of Specification of Letters Patent.

ii -at part of the machine illustrated in 4. 1g. 2:

Fig. a is a section on the line 4-4; of

wherein but a single upper beater is used and wherein the feed conveyer is driven through a train of gears.

Referring now to the drawings by numerals, l designates as an entirety the main frame of the machine 2 as an entirety the corn shelling mechanism, 3 and 4 the lower heaters and 5 the common or primary upper beater, all of which form a part of the complete shelling machine.

A train of gears, designated generally 6 have been provided for driving the primary beater 5 in the direction indicated by the arrow in Fig. 3, themanner in which the gears 6 and the beater 5 are mounted and driven is not new. Such parts as have been heretofore referred to do not form a part of the present invention and are illustrated and described only for the purpose of exemphfying my improved arrangement of parts. a secondary or auxiliary upper beater 7 1s ournaled in the sides of the machine frame 1 forwardly of the primary beater 5 and above the elevated end of the feed conveyer designated 8. Said secondary beater is of a construction common to the art in that the beater sections 9 thereof are mount-- ed on a shaft 10 disposed in parallelism with the supporting shaft of the heater 5.

At present, the feed ccnveyer shaft 11 is driven in the following manner, to wit: A pulley 12 is mounted on an extension 13 of the shaft 10, over which pulley a belt let on crates as shown to advantage in Figs. 2 and 5. Belt 141s crossed and mounted to operate over a driven pulley 15 which forms a part of the mechanism designated generally 6. It

is through rotation of this last mentioned pulley that the secondary beater is revolved. A gear 16 is mounted on the opposite end of the shaft 10 to mesh with a gear 17 mounted at one end of the feed conveyer shaft 11.

Conveyer 8 is mounted at an inclination and may be said to consist of a plurality of conveyer chains 18 disposed to operate in parallelism and in spaced relation With partitions 19 interposed between the several chains. Each chain is equipped with lugs 20 which preclude back-sliding of the corn fed to the machine. The conveyer frame is designated as an entirety by the numeral 21. By the arrangement of a secondary heater in advance of the primary beater and in such proximity to the feed conveyer as shown, it is evident that the corn acted on may be forced to enter the mouth or throat of the machine in a manner precluding waste. Particular stress is to be laid upon the driving mechanism associated with the shaft 10. Were gearing used in lieu of the belt 14, the teeth of the several gears would be stripped, should the mouth or throat of the machine become clogged or obstructed during operation of the machine, This objection has been found to exist in machines now in use. By the provision of a belt, and by driving the conveyer 8 through movement of the beater 7 both the conveyer and the beater, Will, in the event of obstruction cease to operate until such obstruction has been re moved. This automatic stop is obtained by the use of the belt 14in that the belt under the conditions above outlined will leave the pulley 12 and thus idle the mentioned parts. In reduction to practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most efficient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of th advantages of my invention, as defined in the appended claim.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is In a corn sheller feeder, the combination with a main drive shaft having a pulley on one end, a primary feeder positively driven from the main drive shaft, spaced conveyer shafts one of which has a gear on one end, conveyer chains operating over the conveyer shafts, a second feeder shaft mounted over the conveyer adjacent the upper ends, a feeder carried by the second feeder shaft, a pulley on one end of the second feeder shaft and a gear on the opposite end meshin with the gear on the conveyer shaft for positively driving the conveyer when the second feeder shaft is rotated, and a belt surrounding the pulleys on the drive shaft and the second feeder shaft.

In testimony whereof I afiix my signature in presence of two witnesses.
